Have Gun, Will Travel

The Waiting Room (5x24)

Air date: Feb 24, 1962

After a 4 state murder/rape spree, the Wilder Brothers head back to Texas for trial, under Paladin's gun. The slimy pair assure Paladin they have plenty of relatives stationed along the way from Dakota Territory, who'll be delighted to pick off the man in black, because he kills for money, Wilders just kill for fun.
